A method for dynamically distributing speed measurement source of network speed measurement system includes sending speed measurement request message with user ID to control server by user, confirming whether available speed measurement server is existed or not by control server and executing speed measurement task by user if it is, removing user off from user queue when preset maximum execution time of speed measurement task is reached, updating bandwidth and minimum waiting time of each speed measurement server in speed measurement server queue then executing said removing off step cyclically.

The invention relates to a method for controlling equal-gap steel rolling, belonging to the technical field of metallurgy. In the method, a computer control system is used. The method comprises the following control steps of: judging a current steel extraction heating furnace and a next steel extractable heating furnace; reading the action time of a steel extraction machine transmitted by a monitoring sensor of the next steel extractable steel heating furnace as well as a roller table running speed and a practical time interval between the reach of two front adjacent plate blanks to a rollingmill transmitted by a speed senor and a time sensor on a roller table; retrieving a store formula and calculating corresponding waiting time of the next steel extractable heating furnace; when the waiting time is reached, controlling the heating furnace to extract steel; and calculating the next steel extraction waiting time every time steel extraction is finished and determining a next steel extraction heating furnace according to a minimum waiting time principle. Due to the adoption of the method, the tendency to equal-interval rolling is automatically realized by dynamic adjustment, self-adaptation to various complex environments can be realized, the organized production efficiency of a steel rolling line is increased, the stability of the rolling tempo is improved, the energy consumption is lowered, and the problem of the influence on coiled sheet quality caused by unreasonable production organization is solved.

An apparatus, system, and method are provided for automatically minimizing Real-Time (RT) task latency and maximizing Non-Real Time (NRT) task throughput. The apparatus may include a task manager, a determination module, and optionally a tracking module. The task manager may execute a NRT task configured to obtain exclusive access to a resource within a multi-processor environment. The determination module identifies a RT task within the multi-processor environment that shares exclusive access to the resource with the NRT task. Optionally, the tracking module selectively executes or bypasses a preemption point associated with the NRT task in response to the RT task becoming runnable. Alternatively, the NRT task selectively executes or bypasses a predefined preemption point in response to the RT task becoming runnable. In this manner, RT tasks on any processor of the multi-processor environment meet minimum latency thresholds and NRT tasks automatically provide maximum throughput in the multi-processor environment.

A system and method is disclosed for providing single antenna interference cancellation processing with minimum latency. Incoming data frames are processed to generate a plurality of parallel data streams which are then further processed using a parallel single antenna interference cancellation algorithm to reject the signals and to generate a data stream containing only the desired symbols. In various embodiments of the invention, the parallel data streams are processed using a parallel arithmetic logic unit that is capable of operating in single-cycle mode in response to a first control stream and a multi-cycle mode in response to a second control stream. Embodiments of the invention comprise a three port memory interface operable to receive the parallel data streams and to generate a virtual three-dimensional data structure therefrom. In some embodiments of the invention, the virtual three-dimensional data representation comprises a plurality of segmented matrices, with the segmented matrices comprising data corresponding to portions of the incoming data frames. Data elements within the individual segments of the virtual three dimensional data structure can be calculated using data elements contained in a predetermined row and predetermined column of a segment.

Codeword-position-caused encoder latency is reduced by avoiding the requirement for knowledge of the message prior to generating an error detecting or concealing codeword associated with the message. A pseudo error detecting or concealing codeword is inserted in place of the normal error detecting or concealing codeword appropriate for the segment of information to which the error detecting or concealing codeword relates. In order to satisfy the requirement of conventional decoders, the pseudo error detecting or concealing information must match or be appropriate for the segment so that the decoder sees the codeword and message segment as valid or error free. This is accomplished by modifying or perturbing at least a portion of the segment to which the pseudo codeword relates. The invention is particularly useful for maintaining the backward compatibility of audio data encoding formats in which the minimum latency is too long (e.g., computer games, where the player performs some operation leading to a sound, and that sound must not be perceptibly delayed with respect to the operation).

The present invention provides an apparatus and method that increases the utilization by the processors on the shared resources. It provides the minimum latency in a multiprocessor system during exchanging the usage right between multi-processors on a shared resource. The apparatus provides a timer mailbox including a timer. The timer mailbox is at least associated with a first processor and a second processor. The second processor starts to utilize a shared resource to perform a task. According to a predetermined clock cycle number, the timer mailbox issues a signal in advance to notify the first processor of the availability of the shared resource to be utilized by the first processor. It shows the advantages of preventing creating task latency and wasting system resources. The present invention increases the utilization by the processors on the shared resources without extra hardware cost.

A transceiver architecture can contain an encoder and a decoder for communicating high speed transmissions. The encoder can modulate signal data for being mapped in a constellation that is generated based on concatenations of a leech lattice having binary and non-binary codes. The data can be transmitted at a high speed according to the constellation with an embedded leech lattice configuration in order to generate a coding gain. A decoder operates to decode the received input signal data with a decreased latency or a minimal latency with a high spectral efficiency.

Methods and apparatus are disclosed for aligning received data bits in elastic interface systems. Depending upon which one of several alignment modes is selected, data bits can be loaded into FIFO latches on rising clock edges if the data was sent on rising clock edges, on falling clock edges if the data was sent on falling clock edges, or on the nearest clock edge if minimum latency is desired. Alternatively, data bits can be delayed by one or more bit times before loading into FIFO latches to reduce the elastic interface system's sensitivity to drift. The present invention permits a user to trade off factors related to for latency, drift, and skew by choosing among different alignment modes in an elastic interface system.
